1. What about the COST BENEFIT ratio of the “Yellow Jacket” Weather Cap? Our “Yellow Jacket” provides relief valves with the most reliable, positive protection available thereby reducing replacement parts and valve maintenance cost to an absolute minimum. 2. Is the “Yellow Jacket” available with a fat top surface instead of the 45° angle top surface? NO. The slope design sheds debris and precipitation, prevents sagging and deflects damaging environmental particles.  The 45° slope contributes to extended product life and structural stability. The Yellow Jacket offers the same valve protection when installed on an exhaust pipe with a 90° (flat top surface) cut as one with the 45° cut. 3. Is the “Yellow Jacket” available in any color other than Chrome Yellow? YES. However, Chrome Yellow is the most visible color available. Our product may be special ordered* in other colors. Special order shipments will require 2 weeks for the sample color to be approved, followed by a minimum of 30 business days for the first shipment. (Call your distributor for information). 4. Is the “Yellow Jacket” made in sizes larger than 24”? NO. Not at this time. Larger sizes require milling of special molds. Special order sizes will be considered when requested. (Call for information). 5. What are the temperature limits of the “Yellow Jacket” WeatherCap? The “Yellow Jacket’s” functions remain consistent between temperatures of (minus) -100° F to 280° F. 6. What are the pressure limits of the “Yellow Jacket” WeatherCap? NONE. However, PVC solvents and acrylic or polymer paints applied to the exhaust pipe prior to installation of the “Yellow Jacket”, and NOT YET CURED, is likely to cause bonding of the product to the paint. 7. If the “Yellow Jacket” bonds with the exhaust pipe will it rupture under pressure? PERHAPS. So do not apply the “Yellow Jacket” to fresh or uncured paint. If bonded to the pipe, it may rupture in the 20-PSI range. The greater the diameter of the Weather Cap the less pressure required to cause rupture or removal. 8. Are Weather Caps available without the lanyard attachment? NO. However, the lanyard attachment may be easily removed. 9. Will the lanyard/anchor ring device prevent loss of the “Yellow Jacket”? YES. With reasonable PSI the lanyard restraint assures the customer that the “Yellow Jacket” Weather Cap will remain on the exhaust pipe instead of becoming a capricious dangerous missile. 10. Does exposure to high sulfur-content compounds affect the “Yellow Jacket” Weather  Cap? NO. The only chemicals with the possibility of affecting the function of the “Yellow Jacket” are Benzene, Acetone and Trichloroethylene. *Special Orders consist of any items without assigned part numbers.
